It's easier if you just post a failing cmdline, which in this 
case is something like

ldc2 -c .../druntime/src/rt/memset.d -mtriple=armv7-none-eabi 
-mcpu=cortex-a9 -float-abi=soft -O

It's compiling fine without -O; with optimizations, LLVM (10) 
hits an assertion (if built with those enabled, otherwise errors 
out later as you've seen). So might be worth filing an LLVM issue 
about it. [It's also optimized fine with `-float-abi=softfp`.]

Luckily, this rt.memset module seems utterly useless for LDC, so 
you shouldn't need it and can simply delete the source file.

PS: I hope you are using COMPILE_ALL_D_FILES_AT_ONCE=OFF when 
working on the libraries.
